I have a AT&T PC 6300+ (20 MB Disk) with MS-DOS 3.1.  When I run the
format command I get cluster sizes of 8K.  I tried the following method
to modify the BPB:

	fdisk
	format c:
	debug
	l 0 2 0 1
	e 0d      put in the 4 instead of the 10
	e 16      put in the 15 instead of the 08
	w 0 2 0 1
	q
	format c:/s

The sets the number of sectors per allocation to 4 (2K) and the FAT size
to 21 sectors (don't ask me why).  However, when the second format is done
to make it a system disk, the BPB is overwritten with the old data.  I
tried several kludges to correct this and not have to do the final format
but was unsuccessful.  This method is the method in the APRIL PC-WORLD.

Please respond however you can.  The following is my UNIX mail address and
phone number.  Thanks.
